Quick Answer
Is Anua worth it? Yes, for a specific job: Anua is one of the better barrier-focused, soothing-toner brands to come out of Korea in the last five years, and the Heartleaf 77% Soothing Toner earns its reputation. If your skin is reactive, over-exfoliated, or just needs a calm, hydrating first step, Anua belongs in your routine. What it isn't is a full glass-skin system — there's no meaningful pore, firming, or collagen layer here, which is exactly where a treatment-forward brand like MediCube picks up the slack.
Key Takeaways
- The Heartleaf 77% Soothing Toner is the brand-defining product — 77% Houttuynia cordata (heartleaf) extract, fragrance-free, genuinely calming on compromised or reactive skin barriers.
- Anua's strength is soothing and pH-balancing, not active treatment — the lineup is thin on retinoids, meaningful exfoliating acids, or any collagen/firming technology.
- US availability has improved substantially (Ulta, Amazon) but core SKUs like the Heartleaf Toner still restock unevenly, especially during TikTok spikes.
- Best used as a toner-step add-in to an existing routine rather than a full system replacement — most Anua users are running two or three of their products alongside another brand's treatment steps.
- Pairs naturally with MediCube's PDRN and collagen lineup for the firming and pore-refining work Anua's catalog doesn't attempt.

Brand Overview
Anua launched in South Korea in 2016 and spent its first several years as a mid-tier domestic brand before the Heartleaf 77% Soothing Toner turned it into one of the most-recommended K-beauty products on social media between 2022 and 2024. The brand built its identity around a single hero ingredient — Houttuynia cordata, known in Korean skincare as "eoseongcho" or heartleaf — used at unusually high concentration (77%) in a genuinely minimal, fragrance-free formula. That focus is the whole story of Anua: it's a soothing and barrier-support brand first, with a smaller supporting range (the Peach 77 Niacinamide Serum, a heartleaf cleansing oil, a rice-based moisturizer) that extends the calm, gentle positioning rather than diversifying into treatment territory.
For anyone tracking the broader Korean skincare landscape, Anua sits in a similar consumer segment to SKIN1004 — single-ingredient hero, minimal ingredient decks, viral-driven US growth — rather than the multi-step, technology-driven positioning MediCube has built around PDRN and collagen actives.
What Anua Does Well
The Heartleaf 77% Soothing Toner deserves the praise it gets. Fragrance-free, alcohol-free, and formulated around a genuinely calming botanical extract, it's one of the few "viral" Korean toners that actually holds up under repeat, everyday use on sensitized skin — I've recommended it to patients recovering from over-exfoliation or a bad reaction to a new retinoid, and it consistently performs. The Peach 77 Niacinamide Serum is a solid, gentle brightening option for people who can't tolerate stronger niacinamide concentrations elsewhere. Pricing is reasonable (most core products land in the $18–$26 range), the ingredient lists are short and transparent, and the brand has clearly resisted the temptation to pad its catalog with filler SKUs — everything on offer supports the same soothing, barrier-first premise.
Where It Falls Short
Where Anua falls short is treatment depth. There is no meaningful exfoliating acid product in the lineup beyond very mild formulations, no retinoid, and nothing addressing collagen support, pore refinement, or firming — the categories most people eventually want once their barrier is stable. The catalog is also genuinely small: once you own the toner, the serum, and maybe the cleansing oil, there isn't much else to reach for. US stock on the Heartleaf Toner specifically has been inconsistent, with restocks selling out within days of TikTok resurfacing the product. And because Anua is built around one flagship ingredient, the rest of the range can feel like line extensions rather than distinct formulations solving distinct problems.

The MediCube Alternative: What to Add Where Anua Stops
Anua is a genuinely good first step, not a full routine. Once your skin is calm and tolerant, the natural next move is a treatment layer, and that's where I point patients toward MediCube's Glass Glow 7-Day Skincare Set ($77, compare at $136.99) — it bundles the Zero Foam Cleanser, Zero Pore Pads, Collagen Niacinamide Jelly Cream, and Collagen Night Wrapping Mask into a single seven-day routine designed to do the pore-refining and firming work a heartleaf toner was never built to do.
If pores and texture are the priority, the Zero Pore Pads ($24.80, compare $38.99) pair BHA, AHA, and niacinamide in a dual-texture pad — see my full breakdown in the Zero Pore Pads guide. For a firming boost that fills the collagen gap Anua's catalog doesn't touch, the PDRN Pink Collagen Exosome Shot ($28, compare $56.99) is worth reading about in the exosome shot guide. Browse the full Korean skincare collection or jump straight to bestsellers if you want the short list. For the purely soothing step, keep the Heartleaf toner in rotation — it's not a competitor to MediCube's treatment lineup, it's a complement to it. Every MediCube product ships from a US warehouse with a 60-day money-back guarantee and free shipping over $50; check the authenticity guide before buying from anyone other than an authorized reseller. If you're deciding between K-beauty brands generally, our full MediCube review and best MediCube products ranked by skin concern are good starting points, and the how to get glass skin guide walks through where a soothing toner like Anua's fits into the bigger routine.

Frequently Asked Questions
Is Anua's Heartleaf Toner actually worth the hype?
Yes, within its lane. It's a genuinely gentle, well-formulated soothing toner that performs well on reactive or over-exfoliated skin. It is not a treatment product — it won't address pores, texture, or firming, so most people pair it with a treatment brand rather than using it alone.
Can I use Anua and MediCube products together?
Yes, and it's a sensible combination. Use the Anua Heartleaf Toner as a calming first step after cleansing, then follow with a MediCube treatment product like the Zero Pore Pads or Collagen Niacinamide Jelly Cream. They target different jobs and layer well.
Why does Anua sell out so often in the US?
The Heartleaf Toner in particular goes viral in cycles on TikTok, and Anua's US distribution hasn't always kept pace with demand spikes. Core SKUs restock unevenly at Ulta and Amazon; there isn't a dedicated US warehouse the way MediCube's authorized US store operates.
